Yeah I think I understand where you are coming from. In other words, you are prepared to tolerate a certain amount of crap and/or are prepared to sacrifice a bit of independence of thought and action for the sake of the bigger picture of your career.

It is very subtle and you obviously don't need me to warn you of the potential pitfalls but I think I can see where you are coming from.

Unfortunately I don't know how to advise on your specific question. Also, I am a physical scientist so we live in pretty different worlds. I don't know how social science/psychology departments work.

Let us know what you find out.

The word "expect" is the key here. Personally I don't think it is healthy to expect anything from anyone.
I don't think anyone is obliged to care about another person.
Of course, a normal functioning human being will ask you how you are doing or make some reference to you being back at work.
I have to say though that there are plenty of people who hate getting anything resembling sympathy.
When something like this happened to me I simply wanted no fuss whatsoever and to get back to work.
People didn't know that so should they say something to me or not?

Everyone is different and so as I said, it isn't healthy to expect anything. It's a little unfair on them actually.
Just my thoughts.

Ah yes, I forgot about that. OK scratch the supervisor bit......

I have no doubt that some people at some institutions will operate a de facto blacklist but a more likely scenario may be happening.
If I received a CV showing a failed PhD attempt I would probably not want to interview that person for my vacant PhD position unless I was struggling to recruit. If I did interview you, you would expect a very tough set of questions about what went wrong.
From what I have seen, Academics are a pretty risk averse bunch. You may be having problems because of this.

Thanks for the clarification TQ.
I am not in academia now so I can't be sure what advice to give but I can try to put myself in your shoes and give you my thoughts on this if it helps.

Never in my entire career have I spent time worrying about how my job choices will be interpreted by others because I cannot control that. Everything has been about what work interests me personally and how that fashions my career path. My career profile developed from that approach. If at any time I found myself thinking about what potential employers would think about the reputation of the company I worked for, my job title, the uni I got my degree at or who I worked for during my PhD it would raise a massive red flag for me because not one of those things refers to my personal abilities. All of them are based on discriminatory nonsense. It's like the Russell Group discussion from a couple of weeks back. If I had to tick those sort of boxes to work for someone I would have to seriously question whether that was a game I would ever want to play. Why? Because I compromise myself, my choices and my freedom in an ultimately futile attempt to suit some vague idea of what other people want. When you start living your life to suit other people, by definition that would significantly hamper your progress and your personal happiness. I would see that my personal authenticity would be at stake.

As ever I am going to speak honestly here. I think you are at very real risk of making your decisions based on fear. That would be a real shame if true. You can't start your career in this way. You are good. Believe it and trust that others will come to see it too.
My advice for everyone is to focus on being the best at what you do. If you do that, none of the stuff you are worrying about will matter.

Hope that helps.

Your first supervisor doesn't sound lovely at all. She sounds needy, more than a little happy clappy and worse, it sounds like she has pressured you into making a decision which is bad for you. My worst nightmare in a person if I am being honest.

You mentioned in a previous post that you had or still have suicidal thoughts. You need to stop and get professional help right now if this is true. You need to be making decisions which are right for you. In your current state, you absolutely must not be thinking of what is best for her, only what is best for you. You can always come back and finish your thesis when you have recovered,

Please get some professional help for your depression if you can.

Are you worried about being seen as overqualified?
If so, I wouldn't overly worry. I know PhD qualified people who work in call centres and who work as analytical chemists sitting at the end of a machine matching spectra with printouts of expected products.

Researchgate has job listings.
Linkedin is always worth a look too.
The problem is that any job already listed is likely to have been spotted by others.
You might get more luck identifying specific researchers and approaching them with a view to putting in a funding request somewhere.
Alternatively pester your supervisor to recommend you to a group. A good supervisor should help you find postdoc through their own networks.

Doing a PhD because you can't find a job is a dreadful idea.
To add to TOL's advice above, almost every PhD graduate that I know is working on postdocs which are largely unrelated to anything they have experience in. Experience is everything. Specific experience in that particular job surprisingly is not necessarily needed.

Only you can answer that question. I was interested in getting to the bottom of why you were getting rejected.
Personally I don't believe anyone should be doing a PhD with such a poor grade but many people in your position manage to find a supervisor desperate enough to hire them anyway. It's your choice whether to take that risk or not.

24 hours to recive major corrections? That doesn't sound realistic at all. 3 weeks is not on either though.

Yes that's what I suspected. So the feedback you got about having low grades is correct then,
I think this is the equivalent of a 2:2 or grade average 50 to 59%.
I think merit is 60 to 69 and a distinction is above 70 but I might be wrong,

Either way this is probably why you are getting rejections. I dont think it has anything to do with individual module weightings.
Applying to very popular places like Imperial and Warwick is going to be tough as you'll be facing a throng of people with distinctions.
